WATER-VAPORIZING ATTACHMENT FOR INTERNAL-COMBUSTION ENGTNES.

Application filed December 11, 1923. Serial'No. 680,048.

One object of this invention is to provide an automatically controlled attachment for continuously withdrawing liquid-water from the cooling system, vaporizing it, and then injecting the-vapor into the intake manifold of the engine.

A further object is to provide an attachment of the above nature which will automatically shut off the supply of water when the engine stops. I

A further object is to provide a device of the above nature which will be simple, cheap to manufacture, easy to install, compact in size, and very efiicientand durable in use.

With these and other objects in view, there has been illustrated on the accompanying drawing one form in which the invention may be conveniently embodied in practice.

Fig. 1 represents a diagrammatic side view, partly in section, of the water injecting'attachment as it appears when installed upon an internal combustion engine.

Fig. 2 is a longitudinal sectional view of the attachment, shown on a considerably enlargedl scale.

Fig. 3 is a transverse sectional view of the attachment, taken alon the line of Eig. 2, looking in the irection of the arrows.

Referring now to the drawing in which like reference numerals denote corresponding parts throughout the several views, the numeral 10 indicates a body member sub stantially cylindrical in shape, and preferably formed by casting from brass, bronze, or other suitable nonnusting metal. The body member 10 is provided with a pair of parallel longitudinal channels 11 and 12, both of said channels being open at one end as shown at 13 and 14 respectively. The other ends fthe channels 11 and, 12 r duced in, diameter and are connected respectively to the enlarged, inlet andfoutlet ports 15 and 16. The inlet port 15 on the channel 11 is threaded at 17 to receive a pipe section 18, provided with screw threads on both ends, as shown. The lower threadedend of the pipe section 18 is adapted to be engaged by a collar 19, said collar having an inwardly turned flange 20. 20 of the collar 19 holds a flared end 21 of a metal tube 22, preferably formed of co-pper, in tight contact with a conical end23 of the pipe section 18. The pipe 22 leads downwardly and forwardly to the front of The flange the engine where it is connected at 24 to the lower part of the radiator 25. I

The reduced section of the lower channel .ll is joined to -the remainder ofthe channel by a conical tapered portion 27, which forms a seat for the conical end 27 of a valve plug 28, slidable in said channel 11. The middle section of the valve plug 28 is enlarged in diameter at 29 to loosely fit the bore of the rear of the channel 11. The member 28 is provided with a rear section 30, ofconsiderably reduced diameter, upon which aspiral spring 31 is adapted to seat. The other end of the spring 31 engages a T-member 32 screwed into the open end 13 of the channel 11.. V

In order to establish communication between-the channels 11 and 12, a transverse passageway 33 is provided, said passageway having a valve member 34 of larger diameter than the passageway 33, extending through it atright angles. threadedthroughout its length, and is adapted to screw into a threaded hole in the body member 10. The outer end of the valve member 34 is provided with a knurled hand knob 34*, by means'of which said valve member may be manipulated. The valve member 34 is held in any desired adjusted position by means of a nut 35 screwed upon the member 34, and adapted to engage the The valve member 34 is outside of the body member 10. The inner to move the valve member 38 inwardly until it engages the seat 37.

The upper channel 11 is threaded at its open end to receive an adjustable needle valve 38 which has a screw-threaded section 39 intermediate its ends The inner end of the needle valve 88 is reduced in diameter at 4:0 andshas a conical point 41, adapted to seat upon the conical aperture 42 which connects the large rear part of the channel 12 with the reduced forward part thereof. The needle valve 38 extends out through the open end of the channel 12 and is provided with an enlarged head 44 having a slot 45 for engagement by a screw driver or other adjusting tool, whereby the needle valve 38 may bereadily moved to any desired adjusted position in the channel 12.

In order to permit air to enter the channel 12, an air inlet aperture 46 is provided, said aperature 46 being preferably in alinement with the passageway 33 connecting the channels 11 and 12.

An elbow member 47 is adapted to be screwed into the outlet port 16, previously mentioned, and the opposite end of the elbow member at? has a conical extremity 4:8.- The flared end 49 of a copper pipe 50 is adapted to be held against the conical extremity 48 by means of a flange 51 on a collar member 52, screwed on the end of the elbow member 47 The pipe 50 passes rearwardly and upwardly into an exhai'ist pipe 53 which is connected to the exhaust manifold 54 of the internal-combustion engine.

In order to provide a large heating surface for superheating the water vapor as it is. drawn through the pipe 50, said pipe is coiled at 55 Within the exhaust pipe 53, as clearly shown in Fig. 1. The pipe 50, which is held in place by a pair of flanged bushings 55, is connected at its lower end to the T-member 82 by means of a flanged collar 57, similar in all respects to the collars 19 and 52 respectively. The lower leg of the T member 52 is connected to a copper pipe 58 by means of a collar member 59. The pipe 58 extends downwardly,,tforwardly, and upwardly, and is connected at 60 in any suitable manner, to the intake manifold 61 of the internal combustion engine, preferably at a point between the intake port of the enine and the carburetor 62,

In operation, when the engine is started, the strong suction produced by thepistons in the cylinders will be transmitted through the intake manifold 61 to the pipe 58 and into the T-me1nber 32. The suction in the forward branch of the l -member 32 will cause th valve plug 28 to move to the left in the channel 11 against the tension of the spring 31, thereby openin up communica tion between the channel 11 and the pipe 22, and permittinga small amount of water to flow from the lower part of the radiator 25.

The suction from the engine is also transmitted from the rear branch of the "l -member 82 through the pipe 50 into the up acr channel 1:2 of the body member 10. The suction at this point will cause air to be drawn in through the inlet aperture 46 at a velocity determined by the adjustment of the needle valve 38. At the same time, water will be slowly drawn through the pas sageway 83 at a rate dependent on the adjustment of the valve member 34E. The water coming into the channel 12 from the passageway 33 will be aspirated and caused to break up into fine particles by the rapidly flowing stream of air entering from the inlet 46. The commingled air and water spray will then be drawn into the pipe 50 and will be vaporized andsuperheated by the heat of the exhaust gases surrounding the coil 55. The superheated mixture will next pass through the Pmember 32 and the pipe 58 into the intake manifold 61 at the point 60.

@ne advantage of this invention is that carbon deposits in the head of the cylinder will be eliminated, thereby reducing the knocking? of the engine. A further advantage is that the flow of liquid Water to the attachment may be varied at will, thus making it possible to install it upon any size and type of engine.

A still further advantage is that the vaporizing coil 55 is in direct contact with the exhaust gases from the engine. The water spray is thus vaporized and superheated al most instantaneously.

While there has been disclosed in this specification one form in Which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosure but may be modified and embodied in vari' ous other forms without departing "from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims.
